With the vaccine trials still in clinical phases, mitigation of Coronavirus Disease 2019 (COVID-19) relies primarily on robust virus detection methods and subsequent quarantine measures. Hence, the importance of rapid, affordable and reproducible virus testing will serve the need to identify and treat infected subjects in a timely manner. Based on the type of diagnostic assay, the primary targets are viral genome (RNA) and encoded proteins. Currently, COVID-19 detection is performed using various molecular platforms as well as serodiagnostics that exhibit approximately 71% sensitivity. These methods encounter several limitations including sensitivity, specificity, availability of skilled expertise and instrument access. Saliva-based COVID-19 diagnostics are emerging as a superior alternative to nasal swabs because of the ease of sample collection, no interaction during sampling, and high viral titers during early stages of infection. In addition, SARS-CoV-2 is detected in the environment as aerosols associated with suspended particulate matter. Zavondemstat Designing virus detection strategies in diverse samples will allow timely monitoring of virus spread in humans and its persistence in the environment. With the passage of time, advanced technologies are overcoming limitations associated with detection. Enhanced sensitivity and specificity of next-generation diagnostics are key features enabling improved prognostic care. In this comprehensive review, we analyze currently adopted advanced technologies and their concurrent use in the development of diagnostics for SARS-CoV-2 detection.Men show higher vulnerability to severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection (COVID-19) and present with depleted testosterone levels. Reports pertaining to high luteinizing hormone (LH), while diminished levels of in COVID-19 patients negate the hypothalamic-pituitary-testicular (HPT) axis mediated lowering of testosterone. Although not evidenced, high testicular expression of angiotensin-converting enzymes-2 (ACE2), that aids viral entry into cells, may suggest direct viral-testicular invasion. However, secondary inflammation and oxidative stress (OS), owing to SARS-CoV-2 infection, are more likely to impair steroidogenesis. Moreover, blockage of ACE2 aided angiotensin II into angiotensin (1-7) conversion may also affect testosterone synthesis. SARS-CoV-2, by mimicking adrenocorticotrophic (ACTH) hormones, may trigger host antibodies against the ACTH molecules to suppress host stress response. This commentary concisely presents the possible mechanisms by which SARS-CoV-2 infection may affect testosterone levels, which possibly result in compromised male reproductive health.Traditionally, the assessment of endometrial receptivity at transvaginal ultrasound scan has been based on the thickness and the morphological appearance of the endometrium. The objective of this study was to prospectively evaluate endometrial thickness (ET), endometrial morphology and uterine artery Doppler parameters prior to assisted reproduction treatment (ART) in the prediction of pregnancy outcome. This was a prospective cohort study. ET, morphology and uterine artery Doppler (UtAD) pulsatility index (PI) and resistance index (RI) were measured in the mid-luteal stage of the menstrual cycle ultrasonographically, timed with urinary luteinizing hormone testing. A total of 50 women were included in the analysis. The clinical pregnancy rate (CPR) per embryo transfer was 42.0% (n = 21/50). Twenty nine women (58.0%) had an unsuccessful outcome. There were no differences in mean ± SD endometrial thickness (ET) (10.0 ± 1.8 mm vs. 10.5 ± 2.4; p = 0.43), or endometrial morphology (100% (n = 21) vs 100% (n = 29); p = 1.00) between the pregnant and not pregnant groups. Similarly, there were no differences in mean ± SD UtAD PI (2.17 ± 0.83 vs. 2.07 ± 0.81; p = 0.67 or mean ± SD UtAD RI (0.84 ± 0.10 vs. 0.81 ± 0.10; p = 0.30). Ultrasonographic endometrial assessment did not differentiate between those who would have a subsequent clinical pregnancy.The COVID-19 pandemic continues to present enormous challenges for colleges and universities and strategies for save reopening remain a topic of ongoing debate. Many institutions that reopened cautiously in the fall experienced a massive wave of infections and colleges were soon declared as the new hotspots of the pandemic. However, the precise effects of college outbreaks on their immediate neighborhood remain largely unknown. Here we show that the first two weeks of instruction present a high-risk period for campus outbreaks and that these outbreaks tend to spread into the neighboring communities. By integrating a classical mathematical epidemiology model and Bayesian learning, we learned the dynamic reproduction number for 30 colleges from their daily case reports. Of these 30 institutions, 14 displayed a spike of infections within the first two weeks of class, with peak seven-day incidences well above 1,000 per 100,000, an order of magnitude larger than the nation-wide peaks of 70 and 150 during the first and second waves of the pandemic. While most colleges were able to rapidly reduce the number of new infections, many failed to control the spread of the virus beyond their own campus Within only two weeks, 17 campus outbreaks translated directly into peaks of infection within their home counties. These findings suggests that college campuses are at risk to develop an extreme incidence of COVID-19 and become superspreaders for neighboring communities. We anticipate that tight test-trace-quarantine strategies, flexible transition to online instruction, and-most importantly-compliance with local regulations will be critical to ensure a safe campus reopening after the winter break.
